MsiWin32AssemblySupport property

The MsiWin32AssemblySupport property indicates whether the computer supports Win32 assemblies. On systems that support Win32 assemblies, the installer sets the value of MsiWin32AssemblySupport to the file version of sxs.dll. The installer does not set this property if the operating system does not support Win32 assemblies. For more information, see
Assemblies.
